METAL BASE FOR, POLES.

SPECIFICATION forming part of Letters Patent No. 589,079, dated August31, 1897.

Application filed July '7, 1897. Serial No. 643,785 (No model.)

To all whom if; may concern.-

Be it known that I, GEORGE W. GLAZIER, a citizen of the United States,and a resident of Salem, in the county of Essex and State ofMassachusetts, have invented new and useful Improvements in Metal Basesfor Telegraph and other Poles, of which the following, taken inconnection with the accompanying drawings, is a specification.

This invention relates to improvements in metal bases for telegraph andother poles; and it has for its object to make acfirm, strong, anddurable foundation for the lower end of such poles, so as to secure themrigidly to the ground.

The device is equally usefulforapplication to old poles the ground endsof'which may be decayed, as well as for new poles, as will hereinafterbe more fully shown and described, reference being had to "theaccompanying drawings, wherein- Figure 1 represents a top plan view of apole provided with my improved metal base. Fig. 2 represents a sideelevation of the same. Fig. 3 represents an enlarged cross-section onthe line 3 3, shown in Fig. 2. Fig. 4 represents a longitudinal sectiononthe line 4 4, shown in Fig. 2; and Fig. 5 represents an edge view ofone of the sections of the metal base.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

In the drawings, A represents a telegraph, trolley, or similar polewhich may be square, polygonal, or circular in section, as may bedesired, without departing from the essence of my invention. To that endof said pole which is above the ground-surface B are secured thesegmental metal base portions C O O G, which are secured to the lowerendof the pole A by means of bolts D D, going through perforations inthe pole and metal base-sections, as shown.

D D are fastening-nuts screwed on the ends of the said bolts, as shown.

The lower ends of the base-sections Gare placed in a cavity in theground, as shown.

In practice I make integral with the outside of the said base-sectionsstrengthening-ribs .0 G which, besides serving as means to increase thestrength and resistance of said sections against a'lateral straincausedby wind pressure or tension of telegraph, telephone, or trolleywires,also serve in a measure to conceal and protect the heads and nutsof the fastening-bolts D D. Y

For square poles I prefer to use four angular metal base-sections, asshown; but for polygonal or cylindrical poles, more or less, suchbase-sections may be used without departing from the spirit of myinvention.

Telegraph, telephone, and similar electricwire-supporting poles are veryliable to become decayed and rotten where they are em bedded in theground and are then usually discarded and replaced by new ones, whichentails a great loss and necessary expense in providing new poles.

By my invention the old poles may be saved simply by sawing off thedecayed lower end and attaching to that portion of the pole above theground my improved sections, which are afterward inserted in a suitablepost-hole in the ground and firmly rammed in position.

The invention is also applicable as ametal base for new poles of anysuitable form or shape, as hereinabove described.

What I wish to secure by Letters Patent and claim is 1..In 'combinationwith an electric-wiresupporting or other pole, a metal base composed ofsections adapted to be secured to the pole and having outwardly-flaringground portions and ramming perforations in the latter substantially asand for the purpose set forth.

2. In combination with an electric-wiresupporting orother pole, a metalbase composed of sections secured to the pole, said sections havingoutwardly-flaring ground portions, ramming perforations in the latter,and vertical reinforcing-ribs on the outside of said sectionssubstantially as and for the purpose set forth.

' In testimony whereof I have signed my name to this specification, inthe presence of two subscribing witnesses, on this 25th day of Julie, A.D. 1897.
